Implementing serverless functions using Knative Serving

To start building our simple use cases for serverless and event-driven use cases, we have to install Knative with Serving, Eventing, channels, and brokers. In this case, we are going to use the basic options using in-memory channels and Knative Eventing Sugar Controller, which creates Knative resources based on labels in your cluster or namespace. So, let’s start installing Knative Serving in the next section.
